Effects of Different Ratios of Red and Blue Light on the Morphology and Photosynthetic Characteristics of Anoectochilus roxburghii
This paper studied the effects of different light qualities on the growth and photosynthesis of Anoectochilus roxburghii.Under the conditions of uniform temperature,humidity,CO2 concentration and photosynthetic photon flux density,the morphological indexes,chlorophyll and photosynthetic rate and stomatal conductance and transpiration rate of 9 kinds of red and blue LED combination light sources were analyzed.The results showed that the treatment of blue-red 1:1 was more conducive to the accumulation of fresh weight of Anoectochilus roxburghii than other light,and it was also more conducive to the growth of plant height and stem diameter of Anoectochilus roxburghii.White light treatment has a significant effect on the accumulation of above ground parts of A.Anoectochilus roxburghii.The net light and rate were the highest under white light treatment,and negatively correlated with intercellular CO2 concentration.Blue light treatment can promote the increase of stomatal conductance and transpiration rate of Anoectochilus roxburghii,but the net photosynthetic rate is the lowest compared with other light quality.The greater the proportion of red light,the lower the chlorophyll content,and the difference is significant.The blue chlorophyll content has a significantly higher chlorophyll content.
